Kraton based polymeric nanocomposite bioanode for the application in a biofuel cell

The objective of this work is to introduce a nanocomposite based bioanode for biofuel cell application. The as-prepared Kraton/MWCNTs nanocomposite was used as a current enhancer and ferritin (Frt) as a mediator between glucose oxidase (GOx) and the electrode surface. The hybrid anode achieved enzymatic oxidation of glucose by the nanocomposite reflecting an efficient energy conversion from glucose. The resulting Kraton/MWCNTs/Frt/GOx bioande exhibited good catalytic activity towards glucose oxidation along with excellent stability. The maximum current density attained by the bioanode is 1.14 mA cm−2 at the optimum glucose concentration of 60 mM. This enzymatic strategy can be employed to develop other polysaccharide or oligosaccharide fuel cells in which glucose oxidation is involved.

Authors: Turan AS, Ultee G, Van Geenen EJM, Siersema PD Abstract INTRODUCTION: The most commonly used treatment for advanced colorectal adenomas is endoscopic mucosal resection (EMR). The increased number of EMRs since the introduction of the screening program for colorectal cancer has resulted in an increase in EMR-related complications. This review summarizes the current knowledge for the use of clips for the treatment and prevention of complications after EMR. Areas covered: The historical development of clips is summarized and their properties are evaluated. An overview is presented of the evidence for therapeu...
